ecdf_bin {sphunif} | R Documentation |
Efficient evaluation of the empirical cumulative distribution function
Description
Evaluates the empirical cumulative distribution function
(ecdf) of a sample data
at the evaluation points sorted_x
.
This is done through binary search.
Usage
ecdf_bin(data, sorted_x, data_sorted = FALSE, efic = TRUE,
divide_n = TRUE)
Arguments
data |
a vector or column matrix containing the sample. |
sorted_x |
a vector or column matrix with the evaluation points sorted increasingly. |
data_sorted |
is |
efic |
use the more efficient version of the ecdf evaluation? Set to
|
divide_n |
if |
Value
The ecdf evaluated at sorted_x
.
Warning
Be careful on avoiding the next bad usages of the function, which will produce spurious results:
-
sorted_x
is not sorted increasingly. -
data
is not sorted increasingly whendata_sorted = TRUE
-
